9a2e79116d golomb: use unsigned arithmetics in svq3_get_ue_golomb() 
This prevents undefined behaviour of signed left shift if the coded
value is larger than 2^31. Large values are most likely invalid and
caused errors or by feeding random.

Validate every use of svq3_get_ue_golomb() and changed the place there
the return value was compared with negative numbers. dirac.c was clean,
fixed rv30 and svq3.

It's more readable and less prone to breakage.

657ccb5ac7 Eliminate FF_COMMON_FRAME macro. 
FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied
to struct Picture.  Replace by an embedded AVFrame structure in struct Picture.

None of these symbols should be accessed directly, so declare them as
hidden.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
